Sorry, but this item is out of stock and has been discontinued by the manufacturer. The perfect practice and rehearsal lead guitar amp. The K30RX has both overdrive gain and level controls with a footswitchable overdrive. Separate bass, mid-range and treble controls plus reverb give the K30RX a warmth and depth far beyond anything youšve come to expect from a compact amp. 17 watts of RMS power is controlled by three-band equalization and 10"" speaker.
